Using TailwindCss in Storybook 6 with Angular

I am building a component library with Angular (11.2.8) and I try to add TailwindCss and Storybook 6.

I have found different configuration but none of them work. My components have no style when I run storybook.

Here is my configuration :

.storybook/main.js

const path = require('path');
module.exports = {
  stories: ['../projects/storybook/**/*.stories.ts'],
  addons: [
    '@storybook/addon-actions',
    '@storybook/addon-links',
    '@storybook/addon-knobs',
    '@storybook/addon-viewport',
    '@storybook/addon-docs',
    '@storybook/addon-a11y',
    '@storybook/addon-storysource'
  ],
  webpackFinal: async (config, { configType }) => {

    config.module.rules.push({
      test: /\,css&/,
      use: [
        {
          loader: 'postcss-loader',
          options: {
            ident: 'postcss',
            plugins: [
              require('tailwindcss'),
              require('autoprefixer')
            ]
          }
        },
      ],
      include: path.resolve(__dirname, '../'),
    });

    return config;
  }
};

.storybook/preview.js

import '../src/styles.scss';
import { setCompodocJson } from '@storybook/addon-docs/angular';
import docJson from '../documentation/documentation.json';
setCompodocJson(docJson);

    </button>`

tailwind.config.js

module.exports = {
  prefix: '',
  purge: {
  },
  darkMode: 'class', // or 'media' or 'class'
  theme: {
    extend: {
      colors: {
        primary: '#ecc94b',
      },
    },
  },
  variants: {
    extend: {},
  },
  plugins: [require('@tailwindcss/forms'),require('@tailwindcss/typography')],
};

Tailwind styles are not applied

I don't know what is missing in my configuration
